UNITED STATES PATENT OFFICE.

ARTHUR L. OLSSON, OF LOS ANGELES, CALIFORNIA.

SHEET-MUSIC CABINET.

To aZZ whom it may concern Be it known that I, ARTHUR L. OLSSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Sheet- Music Cabinets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in sheet music cabinets and relates more particularly to those which are designed to hold the sheets in separate compartments or racks in order that any clesired piece of music may be taken from the cabinet without disturbing the remaining pieces.

One of the objects of the invention is to provide a cabinet of this type having a plurality of stacked or superposed racks mounted within a casing, said racks supporting the sheets of music and being separable to permit of the sheets being easily withdrawn.

Another object of the invention is to provide in a cabinet of this nature, novel means for supporting the stack of racks in order that they may be easily separated, novel means for separating any two racks and means for indicating the position of the separating means.

As another object the invention contemplates the provision of a cabinet which shall be of extremely simple construction, artistic in design, of a relatively large capacity and very convenient for the purpose intended.

The invention also aims to generally improve devices of this nature to render them more useful, practical and commercially desirable.

With these and other objects in View as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my in vention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a front elevation of my im- Specification of Letters Patent.

proved cabinet, Fig. 2 is a vertical sectional view taken on the plane of line 2-2 of Fig. 1, parts of the structure being broken away to show one of the counterbalance weights, Fig. 3 is a fragmentary vertical sectional view taken on the plane of line 3 3 of Fig. 2, Fig. 4: is a horizontal sectlonal View taken on the plane of line 44 ,of Fig. 2, and Fig. 5 is an enlarged detail view illustrating the construction and operation of the separting means.

Generally speaking, my improved cabinet comprises a case, a plurality of music holding racks stacked within said case, guide means and supporting means for the racks, and separating means, whereby any two of the racks may be separated to permit of the music between them being easily withdrawn or to permit of music being placed between them. Taking up the parts in the order named, 1 designates as an entirety, the case, said case being perferably made rectangular in cross section and including a rear wall 2, side walls 3, and front wall 4: and top and bottom walls 5 and 6 respectively. The front wall is cut away to form a relatively large rectangular opening 7 through which access may be had to the interior of the case. WVithin the case is positioned a plurality of music holding racks 8 which are placed one above the other, as clearly shown in the drawings. Each of the racks comprises a rectangular frame 9 and a plurality of wires 10 connected to the front and rear bars of the frame. These wires extend in parallel relation to one another and are connected to the upper sides of the frame bars. Referring to Fig. 4, it will be seen that the racks are disposed centrally within the case and are somewhat wider than the opening 7 but not as wide as the case. To guide the racks and keep them in their proper positions, I employ a pair of uprights 11 secured to the rear wall 2 and a pair of uprights 12 connected to the vertical walls 13. The rear ends of the racks extend between the uprights 11, and the uprights 12 are adapted to engage the sides of the racks centrally of their ends. The stack of racks is supported by a pair of cross bars 14 which extend through vertical slots 15 formed in the lower ends of the uprights 11 and walls 13 and which are connected adjacent their top 5 of the case.

3 pair ends to the coil springs 16. These springs extend upwardly on the outer sides of the uprights 11 and walls 13 and are connected by means of any suitable fastenings to the Stop posts 17 extend upwardly through the racks adjacent their rear ends to prevent the sheets of music sliding rearwardly too far, and guide wires 18 extend upwardly through the racks adjacent the side bars thereof, and prevent the sheets of music moving laterally from be tween the racks.

Joining now to the means which I employ for separating any two racks in. order that the music between them may be withdrawn or toy permit music being placed therebetween, 19 designates a pair of rails Tshaped in cross section which are secured to the sides 3 of the case 1 adjacent the front 20 wall t. thereof. A runner 20 somewhat triangular in shape slides vertical-1y along each of the rails 19., Each of these runners comprises a vertical bar 21 having its ends extended angularl-y, as indicated by the numeral 22 and notched to receive the rail 19;

and a pair of inwardly converging bars 23 which are formed with bearing openings 24 at their juncture. A rod 25 extends through the openings 2% formed in the runners 20 and engages the vertical bars 21 of said runners, thereby serving to hold them in proper spaced relation and in engagement with" the rails 19. This bar is rotatable within the openings 24 and supports two of upwardly extending arms 26. These arms. are formed with openings adjacent their lower ends through which the rod 25 passes. One pair of the arms 26 is positioned adj aoent one of the walls 13, and

the other pair of arms is positioned adjacent the other wall 13, and the arms of each pair are placed upon opposite sides of the respective walls, as clearly shown in Figs. 3 and 4. These walls are formed with ver tieal slots 27 through which connecting pins 28 extend. These pins connect the upper ends of the arms of each pair and project some distance inwardly beyond the arms. To the inner ends of the pins are connected separating members, generally designated 29. Each member comprises an angular bar 30 and a wedge 31 secured to the lower free end of said bar. These wedges extend inwardly parallel to the side walls of the case and are adapted to engage between any two of the rack rods 32. Each rack carries one of these rods and said rods extend through the side bars of the rack adjacent their forward ends and project into vertical slots 33 formed in the walls 13. The wedges 31 are adapted to engage the rods 32 between the sides of the racks and the walls 13, as best shown in Fig. 1.

To force the separating members toward the racks, I provide a lever 3 lrigidly secured to the rod 25 and provided with an operating handle The front wall of the cabinet is formed with a vertical slot 36 to accon'imodate the lever 31. A pair of depending arms 37 are rigidly secured to the rod. 25 in opposed relation to the separating members 29 and are adapted to en age the lower ends of said members and force the wedges inwardly when the rod 25 is rotated by means of the lever 3-:l. To cause the run ners to move freely along the rails 19 and to cause them to remain in any position in which they are placed, I employ a pair of counterbalance weights 38 which are connccted by ropes 39 to the upper ends of the runners. The ropes extend over sheaves l0 journaled within recesses formed in the cover or top wall 5, and the weights are housed within chambers 41 formed by the vertical walls 412. To indicate the positions of the points of the wedges 31, I provide a pointer which is rigidly secured to the lower end of one of the runners 2L and *which extends parallel to the front wall of the case in a horizontal plane, then upwardly, then again in a horizontal plane,

. as shown in Fig. 3. The arrow formed upon the free end of the pointer is disposed in the same horizontal plane as the points of r the wedges 31.

Having described the construction of my improved sheet music cabinet, it now re .mains to explain the operation thereof:

When. it is desired to place a sheet of music on any one of the racks, the bar is grasped and moved upwardly or downwardly until the pointer comes opposite the desired rack. For the purpose of convenience, it is desirable to have each of the racks numbered and to employ a catalogue,

.ried by the rack upon which the music is to be placed, and the next higher rack, and separate said racks, as shown by the dotted lines in Fig. \Vhen the handle 35 is re- 'leased, the wedges will ride out from between the bars 32 and allow the racks to again assume their normal positions. If it was desired to separate two racks disposed near the bottom of the tier, it would require considerable force to lift the higher racks,

and it is for this reason that I support the tier of acks by the springs 16. These springs permit any two racks being easily separated by allowing the lower rack to move downwardly as the upper one moves upwardly. It will be noted that suflicient space is left between the topmost rack and the top of the cabinet and between the bottommost rack and the bottom of the cabinet, to permit of the racks being spread apart as is necessary when music is being inserted or withdrawn. Any number of sheets of music may be placed upon the racks without interfering in any way with the operation of the cabinet.

From the foregoing description taken in connection with the accompanying drawings, it will be evident that I have provided a very simple and practical sheet music cabinet, which will hold a large number of sheets of music in such a fashion that any desired sheet may be withdrawn or replaced without disturbin the entire stack.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the scope and spirit of the invention as claimed.

Having thus described my invention, I claim 1. In a cabinet of the character described a plurality of music holding racks disposed one above the other in horizontal planes, and means whereby any two opposed racks may be separated, said means including a vertically movable wedge adapted to be forced between any two racks.

2.

6. In a music cabinet of the character described a case having an opening in the front wall thereof, a plurality of racks stacked within said case, uprights secured to the rear of the case between which the rear ends of the racks project, a pair of vertical walls within the case positioned on opposite sides of the racks, said uprights and walls being formed with vertical slots adjacent their lower ends, supporting bars extending through said slots under the stack of racks, and coil springs secured at their lower ends to the extremities of the supporting rods and at their upper ends to the top of the case.

7. In a cabinet of the character described a case, a stack of music holding racks positioned within said case, each rack comprising a frame and a plurality of wires connected thereto, guide wires extending through the racks adjacent the side bars thereof to prevent sheets of music moving laterally from between the racks, and stop bars also extending through the racks to prevent sheets of music sliding too far rearwardly.

8. In a cabinet of the character described a case having an opening in the front wall thereof, a stack of music holding racks positioned within the case, a pair of rails secured within the case on opposite sides of the racks, runners vertically slidable upon said rails,a cross bar journaled in said runners, two pair of upwardly extending arms loosely .eonnected to the cross bar, a depending separating member .pivotally supported by the upper extremities of the arm of each pair, said separating members including wedges, depending arms rigidly secured to the cross bar for forcing said separating members inwardly, and means carried by the racks for engagement by said wedges, 10 whereby any two opposed racks may be separated.

In testimony whereof I aflix my signature in presence of two witnesses.
